    A physician on the Nexphoria review network

    Every Selank prescription is written by a licensed U.S. physician who has reviewed your health questions.

    The Nexphoria clinical standard

    Asked plainly, answered plainly

    Is Selank FDA-approved?

    Compounded Selank is prepared for you by a licensed 503A pharmacy under a physician's prescription, and compounded medications are not FDA-approved. Where a branded, FDA-approved version of the active ingredient exists, that approval does not extend to the compounded preparation. Compounded medications are not evaluated by the FDA for safety, effectiveness, or quality.

    Do I need a prescription?

    Yes. A licensed U.S. physician reviews your health questions and writes the prescription if it is right for you. Everything happens online.

    What bloodwork is required?

    A free at-home blood kit ships with your first order, so your physician sets your Selank dose against your numbers. At week 12, the same full panel is drawn again, included, and your dose is adjusted from what changed.

    What should I expect in the first weeks?

    Day 1: Your first spray. Most people feel it within the hour. Everyone responds differently, which is why your blood panel at week 12 is part of the plan and your dose is adjusted from it.

    How is it billed?

    You buy a block of time, paid up front: one month to try it, or three, six or twelve months at 10, 15 or 20% less per month. Longer terms include more blood work. When your term ends, renewing is your choice.

    Your week-12 blood panel

    See how your body is responding.

    This peptide works on the brain. Your week-12 panel checks thyroid and cortisol, which shape mood and focus on their own, so your physician can read the whole picture.

    A full panel of 24 markers is included in your plan. See every marker and why it is there

    What your physician checks first

    TSH · Free T4 · Cortisol

    Your physician checks for

    • Current psychiatric medications
    • Pregnancy, or planning one

    More than the medication

    Your medication, your physician, and the blood panel behind it.

    Safety first

    Is it right for you?

    Concurrent psychiatric medication (physician review)

    Compounded preparations are not FDA-approved, and the FDA does not review them for safety or effectiveness. Where an active ingredient is FDA-approved in other products, that approval does not extend to a compounded preparation. Prescribed only where a licensed provider determines it appropriate.
